It's been a few years since I went through all the Deep Dives / Due Diligence (DD).

Yes, the paper money is only a fraction of the available digital dollars they fabricate constantly. As you may have seen, some banks are NOT able to give their clients large sums of cash ($5,000 - $10k) upon request. The paper just isn't there which tells you that there's too much fake digital money floating in the ethos.

The Fed Reserve is painted in a corner. They can't raise interest rates nor can they lower them without major detrimental consequences.
